BOBBIN;

Specification of Letters Patent.

Patented March 9, 1909.

To all whom it may concern:

Be it known that I, JAMES ROBERT COE, a citizenof the United States,residing at Ansonia, county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Bobbins, of which Myinvention consists in a yarn carrier orv bobbin for spinning or twistingapparatus.

The object of my invention is to provide a bobbin which will not splitand which will not be liable to injury when introduced in or thrown. outof a shuttle, andwhich will cost less to manufacture than the bobbinsnow in use. I

Bobbins have heretofore been made of dried wood, with a heavy wire Woundaround the base of the bobbin, which wire is intended to cooperate withthe shuttle to hold the bobbin in place when in the shuttle. Suchbobbins are open to the objection. that the wood absorbs moisture, andis, therefore, liable to expand, contract and split, and the wire to bedisplaced by such expansion, and

contraction, and the blows to which the bobbin is subjected inintroducing it into and throwing it out of the shuttle.

My improved bobbin is made in two parts,

the upper part intended to receive the yarn or thread, is made of paper,or other noncellular material having no pores for the ab sorption ofmoisture, and the lower part, which is intended to cooperate with thshuttle is made of spun metal. The accompanying drawings will serve toillustrate my invention, in which- Figure 1 is a vertical sectionalview. Fig. 2 a view in elevation, and Fig. 3 a cross section.

' The bobbin as a whole consists of a base portion or head 1, and atapered shank or.

adapted to interlock with correspondingly grooved parts of a shuttle, inthe usual manner. The lower part of the head is bent upward to form aflange surrounding an opening 4 to receive a pin on the spinning frame.

The upper portion of the head has a tubular extension 5, over which; thelower end of the shank 6 is placed and secured in any'suit portion isadapted to fit over and may be attached to the suitable manne' I wish aunderstood that i do not limit myself to the precise form of thepartsshown.

base portion or head in any Having thus described my invention, I

claim:

1. A bobbin comprising a non-cellular shank, a spun metal base having anextended upper portion to cooperate with the lower portion of the shankand an extended lower portion below the. shank provided withcorrugations. v D

2. A bobbin comprising a, tapered shank,

and a spun metal base, said base having a tapered portion extendingupward within the shank and a cylindrical portion extending below theshank having corrugations.

upon its surface.

3. A bobbin comprising a tapered shank, and a spun metal base, said basehaving a tapered upper portion extending within the shank, a cylindricallower portion below the shank having exterior corrugations and aninturned flange adapted to surround a pin on the spinning frame.

In testimony whereof, I aflix my signature, in the presence of twowitnesses.
